Abstract: The impact of preheating and dilution on methane/air non-premixed flame stability are studied experimentally. Six preheating levels are considered for initial reactant temperature between 295 K and 850 K in a round jet configuration. Four diluent gases are added on the air-side, either CO 2 , N 2 , Ar or a (CO 2 + Ar) mixture having the same molar heat capacity as N 2. For undiluted flames, jet transition velocities between attached and lifted states are investigated depending on initial reactant temperature. …
